Get the Masonmug. A very quiet, but cool girl. Usually with dark hair and certain eyes. She always looks mad, but in actuallity, is usually in a good mood, and only looks pissed because she is in deep thought. She'll have a decent body, and face, but she makes up for that with her wicked sense of humor. When you see her around with other guys, you'll get extremely jealous. If you ever hear a high-pitched laugh, a deep voice, or a very loud yell, you'll know it's a Mason. Voices her sexual tensions about a lot of guys, but when she likes a guy, she's the sweetest girl you'll ever have, if you ever get a Mason, dont let her go. And if she ever asks you out, you'd be a fool to say no.
"Look at that girl, she is such a Mason."
Friend "Who was that girl that talked about blowjobs in science today?"
"Oh, that was Mason, but she was just jokeing."
"Who was that guy you were talking to earlier today?"
"... Um, that was Mason, and she's a girl..."
"You're so lucky, you have the sweetest girlfriend ever."
"I know, she is such a Mason".

Get the Masonmug. Mason is one of the most althletic kids you will ever meet. He is definitely a keeper and you shouldn't break up with him. He likes Viedo games, likes to hang out with his friends, and loves to play a lot of sports. A Mason is very energetic and is super cute. He has amazing hair and almost always has a six pack.

Get the Masonmug. Mason is a guy who you think is an utter asshole at first, but after about a month of dealing with him, he starts to grow on you. He’s the kind of person to send you an extremely worrying meme that he found on Reddit at 4 in the morning. He’s not much for being emotionally vulnerable or showing how he truly feels, unless it’s in a very specific meme. If you try to be vulnerable with him he’s either going to laugh or awkwardly make a terrible joke about your extreme trauma. Gotta love the dude tho.

Get the Masonmug. Also known as May May, this is a big lad who's pretty nice until you get to know him. He loves wood, cooking, hockey, and alternating between being chill and being an ass. He also says "eh" a lot and subconciously repeats everything he says in a whisper.
